Abstract
Since resistance of the causative organism of American foulbrood,
Paenibacillus larvae subsp. larvae, to oxytetracycline (OTC) is
becoming widespread in the United States, we began a search for
effective alternative antibiotics. We investigated the sensitivity of
P. l. larvae to 27 antibiotics, which were primarily ones already
registered with the US Food and Drug Administration for agricultural
uses. Bacterial resistance to OTC also conferred resistance to other
tetracyclines, although the level of resistance varied. The most
active antibiotics screened that are currently used in agriculture were
erythromycin, lincomycin, monensin, and tylosin. Rifampicin
was by far the most active antibiotic tested, but since it is used
against tuberculosis, registration of this material for agricultural use
is unlikely.
Hope this helps.
